I removed the old oil out of hubs.going to replace oil,put new brake fluid in the system.might get the rotors turned.

I finished my trailer maintenance a couple of days ago. Changed the oil in the oil bath. Pulled hubs to inspect spindles, bearings and seals. Inspected brake pads and rotors. Re-assembled the running gear. Lubricated the pivot points on the coupler. I have the Reliable surge break which is no longer manufactured. I know I need the bushings (plastic) on the roller pins in the surge break. I asked the dealer to get a few for me but I have not followed up on that. My fear is that they are no longer available.

I've already stated looking into contingency plans on the Reliable coupler parts. Not looking too good without surgery. So what's the consensus on bearing oil these days? I'll be doing my trailer work this spring when the boat's on the lift again. It's so much easier to work on the trailer without the boat. I'm also strongly considering changing out my 5 year old Marathons this spring too.

There are a ton of people who hate the Blue Tops most claiming that they didn't last. If you do some searching you'll see most of these people didn't know what they were doing with the batteries and didn't have a decent charger designed for the technology.

I'm going on season 4 with mine, no issues. I like them due to the no spill design and ability to mount them just about anywhere. I also like the battery trays that are available and their compact design. They do cost more and if you're in love with your 20 year old or cheap battery charger they are not for you.

As for Interstate and Diehard.... had nothing but good luck with both. They're cheap but you will most likely have to live with the large black plastic boxes and deal with the battery acid that tends to somehow always make it's way out of the battery. They are however a very cost effective solution.
